<p>I'll have to look more closely at the thread, but it seems clear that we can't out-and-out remove the feature yet without more work on a replacement. Warnings might be ok, though I think that's not obvious to me (e.g., I don't know that servo wants to get a warning on each build)</p>

<p><span class="user-mention silent" data-user-id="116083">pnkfelix</span> aren't you, de-facto?</p>
</blockquote>
<p>so this was indeed why I talked to <span class="user-mention" data-user-id="116083">@pnkfelix</span> about it, but I am happy that he brought it up here and I'd like to hear from others if they think they want the role; along those lines, we also created <a href="https://github.com/rust-lang/compiler-team/issues/184" target="_blank" title="https://github.com/rust-lang/compiler-team/issues/184">a design meeting proposal</a> to talk about heping to further define the roles in the team, including what <em>exactly</em> co-lead means. (In my view, it means a few things: most obviousy representing the team in various official places, but also mediation and a sense of "buck stops here", i.e., generally trying to ensure that things are proceeding as they ought)</p>
